lowing is a full, clear, and exact description of the same. i

The invention relates to improvements in power transmission from a car axle for generating electric current, as described in the present specification and illustrated in the accompanying drawings that form part of the same.

The invention'consists essentially in the novel construction and arrangement of parts, whereby an electric generator suitablysugported is driven bg' power transmitted cm the axle throng a flexlble connection with one end of the axle.

The objects of the invention are to increasethe efliciency of the generator by insurmg a constant 'generation of current while the train is in motion and thus obvi ate the troubles incident to irregular drives, to eliminate, the use ofbelts as a power "transmitting means from the axle to the generator, and

generally-to devise a simple, compact and durable electric equipment for the. generation of. current for lighting and other uses'withinthe car.

In the drawings, 1 is a sectional showing an electric generator attached to the under side thereof, and a. power transmitting device beneath the generator artially in section and attached to the a e of the car. Fig. '2 is a vertical sectional" view on the A-B in Fig. 1, lookin outwardly. Fig.

eferring to the drawings, 1 'is the car '55 member ofthe ball joint 8.

' 4 is an electric erator having ro'ecti u wardly .ang dentrally from its top si e, t e other member of the ball joint 3, thus suspending said electric enerator 4 from the body of the car by a exible connection;

5 are cushion springs introduced between the top side of. the electric generator and the plate 2. The particular form of suspension of the said electric generator from the car body is important, but not essential to the invention, as it maybe supported in many other ways, in fact the support from the said car body of said generator may be quite rigid wit out departing from the spirit of the invention.

6 is the armature shaft. 7 is a bevel pinion,mounted on the lower end of the said armature shaft 6.-

8 is the gear case having the flanges 9 rigidly secured to .the under side of the generator4 and divided inthe interior thereof into the pinion' chamber 10 and. the gear chamber 11.: I

39 is a bevel gear wheel fixedly mounted on the shaft 17 within the gear chamber 11 and coacting with the pinion 7, said gear be ing rotated by the rotation of the car axle 29 through the telescopic shaft. 40 are oil rings suspended on the shaft 17 on each side of said gear wheel and hanging down into the bottom of the gear case which forms an oil well;

In the operation of thisinvention, as the car travels, the axle 29 is rotated, which rotates the cap 25 and consequently the telerotates the gear wheel 39, which coacts with the pinion 7 thus driving the armature shaft 6 and generating current. During the of course, swing on its pivot on rounding curves, besides, will to a, certain extent jump, in other words, the said truck of thecar 1s movement caused by any unevenness in therailwa or curves of the same and theresult 0 this is that the end of the axle, on

In this connection, it may be atoi' to theitruck frame, these rods will be merely form a connection between said truck and said generator, so that the'generator frame must. move with every movement of the truck, however, it is entirely optional in'regard to the use of these rods, though under some conditions they may befound quite an important-detail of construction.
